tvtime, can not change channel but used to ...... (resolved)

[m1rage]

Hi everyone,

I've been trying to get this to work for a couple of hour now and googled to find something but I can't get it to work.

I have a WinFast 2000 Deluxe and I'm using gentoo-dev-source (2.6.3-r1)

I don't know where my problem is coming from so I'll start from the begining when I started with that card this morning.

I emerge tvtime, it didn't work right away because I didn't know what I needed to compile in the kernel. I found what I needed so I enabled the bit-banging algo and the other one :

#
# I2C Algorithms
#
CONFIG_I2C_ALGOBIT=m
CONFIG_I2C_ALGOPCF=m

Also compiled bttv
# Video Adapters
#
CONFIG_VIDEO_BT848=m

I compiled the kernel and rebooted. Once that was done I re-emerged tvtime and opened it, it was working but not correctly so I did :

modprobe -r bttv
modprobe bttv tuner=2 card=34

After that tvtime was working ok and I was able to change channel, but I didn't have any sound. I thought I missed something when compiling the kernel so I did :

cd /usr/src/linux
cp .config ~/.config
make mrproper
cp ~/.config .config
make menuconfig (checked everything to make sure it was ok and it was)
make
make modules_install

I made a backup of my bzImage to bzImageTVNoSnd and copied the new bzImage over.

I rebooted to the new kernel and started tvtime and I was stuck at the last channel I checked when I was able to change channel...I am able to use the up/down arrow and I see the number appearing but the channel never change (it looks like it is though)

I rebooted to the old kernel and I'm having the same problem. What's the problem there?

Here's the output of dmesg

I really don't know, I'm guessing it's coming from that tv_set is NULL but I don't know how to fix that since I don't even know what I did to get that error once it was working....

Any ideas?

Hi Malakai,

Thanks for the reply, that's how I got it to work the first time but then I was unable to change channel for some reason.

After reading this thread

https://forums.gentoo.org/viewtopic.php?t=138741

I decided to give 2.6.4 a try and it's fixed now...I guess I would have gotten the same result applying the quick fix described in that thread. I still don't understand why it happened though as it did work with 2.6.3 for a while.

Anyway finally it's working
